Silver-decorated and palladium-coated copper-electroplated fibers derived from electrospun polymer nanofibers

•Silver and palladium fibers were fabricated by the combination method.•Fiber morphologies and elemental compositions were analyzed by SEM, EDX, and XPS.•The high electrical performance of the fibers was exhibited with transparency.

Here we introduce novel methods of forming silver (Ag) and palladium (Pd) fibers. The Ag and Pd fibers are fabricated by the combination of electrospinning, electroplating, and ion-exchange techniques. Their properties are characterized by scanning electron microscope with energy dispersive X-ray spectroscopy, sheet resistance meter, UV-Vis spectrophotometer, and X-ray photoelectron spectroscope. These non-woven metal fibers are free-standing and film-shaped with high electrical conductivity, as well as flexibility. Such properties are attractive for future applications of these materials in various electrochemical processes.
